We generally carry two isobutane stoves, whatever lightweight pot we dare risk losing or damaging from our modest kitchen collection and ... an iron pan.
Yep, for all the high tech gear we carry an iron pan (8" or 10" depending upon how many in our party), a cooking luxury we will not be denied. An iron pan is 1) as good as a third stove (albeit heavier) in that it'll keep prepared foods warmer longer, 2) cooks better and more evenly in my opinion, 3) and, properly 'seasoned', is no more a hassle to keep clean than the finest and newest teflon.
It also comes in handy for swatting black flies although the noise, somewhat like a golf ball bouncing off the pan, can be annoying and care must be taken if you swat anything while it is perched on your camping partner's head.
Otherwise, we're minimalists ... except for the wine.
